      Guys, i actually got the following which still work:
      z = -4 ; y = 8 ; x = 1
      all are variables which fit in the equation. Strange that the teacher did't show that there areother solutions to this...?

    Mr. McLogan,
    I passed my college placement exam because of your videos. I am a non-traditional student who lost nearly all mathematical knowledge after high school. Thank you so much for uploading all of these great videos. They have been a tremendous help. I also passed my first college-level math exam with a 90 the other day.

    When you multiplied equation A and B how did you come up with -5 and 2?

    • @brianmclogan
      @brianmclogan  7 лет назад +13

      Those are the scalars that allow me when multiplied to obtain the same coefficients for y so that y can be eliminated when I combine the equations

    • @Brobecreative35
      @Brobecreative35 6 лет назад +4

      Betty Echavarria oh because basically when he did A he was multiplying a negative by negative giving him a positive, so to cancel out y he need B to be negative and positive 2 was a good solution for that

  • @tristanfoss7469
    @tristanfoss7469 3 года назад +2

    In fairness to teachers, no matter how you do or describe these types of equations, they always take forever and have a lot of variables that can accidentally be screwed up. In my class, no one liked this method because even if you can understand how to do it, it still takes forever. If you're clever, you can usually come up with usable shortcuts to math, but you always have to figure out X, Y, and Z the hard way.
